Integrated delivery creates value at the handovers, where information, risk and responsibility pass from one party to the next. It works when the critical decisions are made with the next stage in view and each party remains clearly accountable for its own scope.

The hidden cost of handovers

A typical Sydney residential project passes through many hands: a buyer's agent or landowner, a planner, an architect, engineers, a certifier or council, a builder and dozens of trades, a lender and valuer, and finally a selling agent. Each party is usually competent at its own job. The problems appear between the jobs.

At every handover, the receiving party rebuilds its understanding of the project from documents prepared for someone else. Assumptions are lost. Decisions that made sense to the previous party look arbitrary to the next one. Some are reversed, at a cost. None of this shows up as a line item, which is exactly why it is so often underestimated.

Four handovers where value leaks

1. From site to design

The commercial reasoning behind a site purchase (target buyer, price point, yield) often reaches the architect as a one-page brief. Without the feasibility behind it, the design can drift toward something more ambitious or less saleable than the numbers support. Integration means the designer sees the feasibility and the feasibility sees the design, while it is still a sketch.

2. From design to cost

Designs are often priced for the first time after approval. By then, an expensive structural move or a basement that needs extensive rock excavation is embedded in an approved scheme. Early cost and buildability input, from someone who will actually have to build it, keeps design ambition and budget in the same conversation. We explore this in why early buildability changes a feasibility.

3. From approval to construction documents

Approval drawings show what may be built; construction documents show how. Gaps between the two produce variations, delays and arguments. When procurement lead times, product data and installation details are considered during design development, the approved scheme is easier to document and price accurately.

4. From build to sale

Buyers want evidence: who designed and built the home, what was approved and what is included. If the sales team assembles that story only at launch, it is assembled from whatever documents are available. When sales input arrives early, the product is shaped for the buyer and the evidence is collected as the project goes.

What integration should not mean

Integration is sometimes sold as a single point of responsibility that makes everything simpler. In practice, blurring responsibility creates its own risks. Good integration keeps three things intact:

  • Separate scopes and contracts. Design, construction, credit assistance, fund services and agency services are different activities with different legal duties. Each should be contracted with the entity that actually provides it.
  • Licences that match the work. A builder's licence, an architect's registration, a credit licence and a financial services licence each cover specific activities. Clients should be able to see which entity holds which credential, and check it on a public register.
  • Independent checks. Certifiers, valuers, quantity surveyors and the client's own advisers remain independent. Integration should make their job easier, not replace them.

This is the model AUD Group follows: the group coordinates, and each operating business contracts and provides services through its own legal entity and authorised scope. The group structure and dated company sources set out who provides what.

How it compares with other delivery models

Most residential projects use one of three broad approaches:

  • Traditional (separate appointments). The client appoints the designer, then tenders to builders. It gives competitive pricing and independent design advice, but cost certainty arrives late and the client manages every interface.
  • Design and construct. One contractor takes responsibility for design and construction. Interfaces are simpler, but design decisions may favour the builder's cost over the client's long-term value.
  • Coordinated specialists. Separate specialist businesses are appointed on their own terms but share information and plan around one project strategy. It aims for the early cost and buildability input of design and construct while keeping independent design and clear accountability.

No model is right for every project. A simple home on an easy site may be well served by a traditional tender. A constrained site, a development with finance and sales risk, or an owner without time to manage interfaces usually benefits from more coordination.

One business or several?

You do not need to use every service to benefit from coordination. The most useful question is: which handovers carry the most risk on this project? If it is the jump from site to design, start with a feasibility and design review. If it is cost certainty, bring construction input into design early. If it is funding, make sure the finance conversation uses the same information as the drawings and the contract. If it is the sale, bring sales input in before the design is fixed.
